The fire rat clan has produced two evolutions: most walk the fire-washing road — fur ever whiter, woven into cloth that saves lives. A very few walk mine: the fur does not whiten. Instead, the whole body begins to shine.
The clan calls it the turning-back of light. A fire rat eats fire-moss all its life, they say, and the fire-breath gathers in the pelt; gathered past all limit and unable to burn outward, it turns back — and becomes light.
As a Firelight Beast I stand ten times my old size, and a layer of warm light rides forever on my fur-tips. Wherever I walk, three zhang of the world is bright. No heat. No scorch. Only brightness — a lamp that walks.
The Keep assigned me the night patrol.
Three streets, nine lanes; I walk them dusk to dawn. With me on rounds, even the night watchman spares his clapper — when a lane-mouth brightens, everyone knows: the Firelight Beast is passing; all is well. When children fear the dark, their parents say: count the light. When it has passed three times, morning comes.
Decades of this work taught me one settled truth: darkness is not fearsome. Darkness is merely the absence of light; carry light into it and it retreats. A law of nature. No exceptions.
Until, three years ago, I met the black-bright thing.
The kind the ghostfire brothers describe: black with a shine to it, bright enough to hurt, and in its glow a person's shadow moves half a beat before the person. It is not darkness. Darkness is a nothing. This is a something — an inverted something.
Our first encounter was at the edge of the wrongful fire in the east lane. As always I cast my light across, to give the firefighters sight — and the rim of my light touched the rim of it.
And I watched my light being drunk into it, one mouthful, the way mud-ground drinks water.
A patch of my fur-tips went cold. The light there has never grown back.
But in the instant of the swallowing — the last moment before my light was severed — I looked along my own beam, into its interior.
Listen carefully. Inside, it is not black.
Inside, it is entirely light. Light pressed layer upon layer, packed solid: lamplight, ghostfire-light, snow-glare, the particular light that lives in children's eyes — all of it crushed flat and stacked in courses, like… grain stacked in a granary.
It is not darkness. It is stolen light, piled until it reads as dark.
Light piled into darkness — do you feel how terrible that sentence is? One lamp is light. Ten thousand lamps crushed flat and stacked without a seam between them: that is the blackest black there is. The mouthful it took of me was not meant to extinguish me. It was meant to collect me. Into the granary.
Since that night, my patrol carries one extra duty: counting light.
Every lamp in the Keep — whose house, how bright — is entered in my ledger. Any night a lamp dims wrongly, I swing past for a look. In three years the ledger has lost seven lamps. Seven households — not out of oil, not wind-blown: their lamps simply grew thin. Thin as a film. And within a few nights, the family still lit the lamp, and the lamp could no longer manage brightness. Those seven households have all gone listless since — sparing of words, asleep at dusk.
When a lamp's light is collected, the little light inside its people thins with it.
I drew the seven locations for the medicine-basket boy. They investigated: all seven wells tested positive for furnace-ash.
Now I travel west with the company. By night I am the party's lamp. By day I work at something else —
an art long lost to my clan, whose old name is Turning Light to Break the Granary: twisting my own light into an awl.
For if that thing is a granary, and everything stacked in it is plundered light —
then someday, some lamp must burn bright enough to bore the granary open.
And in the moment it is holed, all the light pressed inside — three years of it, thirty years, three hundred — will pour out at once.
I want to see that.
I suspect it will be the brightest night this darkened world has known in three hundred years.
